The Kantek MAXVIEW LCD Monitor Magnifier is constructed of a high-quality Fresnel lens that enlarges the image on the screen. The Fresnel lens technology replaces the conventional large and heavy glass optical lens, providing a versatile thin light-weight magnifier option. The Fresnel lens is flat on one side and has ridges on the other, consisting of a series of concentric grooves which act as spatial refracting surfaces that bend the light rays to magnify the visual image. The lens is specifically designed for LCD monitors, constructed of an optical grade acrylic with a high groove density for a sharp enhanced magnified image enlarged up to double the size. The MAXVIEW Magnifier features an innovative, proprietary attachment mechanism to easily adjust the spatial distance between the LCD and the Fresnel lens. (U.S. Patent #7495846) Magnification levels are a function the spatial distance; the further the distance of the lens from the LCD, the larger the magnification.
